He began fundraising for Movember in 2024 by running 5km (3.1 miles) every day throughout November, raising more than £2,000 for men’s health causes.
This year, his mission has evolved beyond fundraising.
“Men have a funny way of talking,” he said. “It’s not always deep heart-to-hearts, sometimes it’s just standing beside someone, going for a run, or having a kickabout.
“That quiet kind of support can be enough to remind someone they’re not alone.”
Three weeks ago, Mr Brewer set up the Brotherhood Run Club, which already has more than 70 members.
During Movember, he will be running 60km (37 miles) every week in a bid to continue raising awareness.
“To any man struggling, you’re not alone,” he said.
“There’s no shame in opening up. Being vulnerable is one of the strongest things we can do.”
